Thanks for this information!

Nice to have some reusable code for versioning... About the components question again: I played around a bit, and I think I now more or less have comprehended this. I guess for a package XXX with components YYY and ZZZ, one could set variables XXX_HAS_YYY and XXX_HAS_ZZZ and then use a loop like this one in the XXXConfig.cmake file: foreach( component ${XXX_FIND_COMPONENTS} ) if ( XXX_HAS_${component}) set ( XXX_${component}_FOUND TRUE ) else( XXX_HAS_${component}) if ( ${XXX_FIND_REQUIRED}) message(FATAL_ERROR "Required component ${component} not found!") elseif ( NOT XXX_FIND_QUIETLY) message(STATUS "Component ${component} not found!") endif ( ${XXX_FIND_REQUIRED}) endif ( XXX_HAS_${component}) endforeach( component ) Correct?
